ROLLER-BEARING.

Application filed December 30, 1911.

To all whom it may concern:

Be it known that I, DAVID E. LYoNs, re siding at Los Angeles, in thecounty of Los Angeles and State of California, a citizen of the UnitedStates, have invented or discovered certain new and useful Improvementsin Roller-Bearings, of which imp-rovements the following is aspecification.

The invention described herein relates to certain improvements in rollerbearings of the type having bearings or working rollers mounted so as toroll around a suitable hearing surface and suitably spaced by idlers ofless diameter than the working rollers and supported with their axes thesame distance as the axes of the working rollers from the axes of thebearing.

The invention is hereinafter more fully described and claimed.

In the accompanying drawing forming a part of this specification isshown a sectional elevation of my improved bearing.

In the practice of my invention the bearing member 2, which ispreferably the outer surface of a hollow cylinder or sleeve adapted tobe secured in any suitable manner on a shaft axle or other supportingmember 3 is provided with spaced collars 1 and 12 between which theworking rollers are arranged. These collars are made of such a thicknessor height relative to the bearing surface 2, as to permit of theformation of grooves or raceways 4: in their inner ends for thereception of the ends of spacing rollers 5. The grooves or raceways areformed such a distance from the bearing surface 2, that shoulders orabutments 6 are formed which will afford bearings for the ends of theworking rollers, which rest upon the bearing surfaces. As the lowerwalls of the raceways are employed for supporting the spacing rollers,the heights of the shoulders from the bearing surface are soproportioned relative to the diameter of the spacing rollers, saiddiameters being less than that of the working rollers, that the spacingrollers will be supported out of contact with the bearing surface 2 andwill also be concentric with the working rollers, c. 6., the axes of thetwo series of rollers will be equidistant from the bearing surface. Insuch a construction the area of the shoulders or abutments in contactwith the ends of the workin rollers will be less than half the areas ofthe ends of such rollers. This is an Specification of Letters Patent.

important feature of my improved hearing as experience shows that whenthe bearing areas of these two elements are relatively large andundesirable heating is liable to occur. It will be observed that theupper walls of the raceway are cut back, so that the ends of the rollerswill not contact therewith. The fianges 8 which form the upper wall ofthe groove or raceway serve as retaining rings for the spacing rollersand extend over the ends of such rollers sufliciently far to prevent adislodgment of these rollers but not sufficiently far to contact withthe ends of the working rollers or the ends of the bodies of the spacingrollers, when the latter are formed with reduced journal portions 9, asshown.

As the distance between the inner ends of the upper walls of theraceways is less than the lengths of the spacing rollers, one of suchwalls should be made removable to permit of the placing of the spacingrollers in position. In the construction shown, the upper wall of theraceway in the collar 12 is formed by the inner end of a ring 14:, whichis held in position in the collar in any suitable manner, as by thethreads, or it may be shrunk on or forced to proper position by asuitable press. The inner end of this ring forms, as stated the upperwall of the raceway 13 and serves to retain the ends of the spacingrollers in position.

When the ends or journal portions of the spacing rollers have the samediameter as the body portions, shoulders 15 are formed in the racewaysof a height less than the diameters of the spacing rolls, so that whilethey perform their function of preventing endwise movement of thespacing rollers, the areas of contact of the rollers and shoulders willnot be sufiicient to cause frictional heating.

I claim herein as my invention:

A roller bearing consisting of working rollers and intermediate spacingrollers in combination with a member having a cylindrical bearingsurface and provided with peripheral bearings for the spacing rollers,and with end bearings for the working rollers adjacent to the bearingsurface, said bearings being not greater than half the diameter of theworking rollers and with retaining rings extending inwardly over theends of the spacing rollers but not into contact with the ends of theworking rollers, thereby avoiding an increase of the end bearing of Intestimony whereof, I have hereunto the Working rollers beyond half theareas lolf set my hand.

the same, said arts for one end of the ro ers being integ i'al with thebearing surface DAVID LYONS' While the retaining ring for the oppositeWVitnesses:

ends of the rollers is removable to permit of G. G. TRILL the placing ofthe spacing rollers in position. ALICE A. TRILL.
